COMPANY,'OF BROOKLYN, NEW

FASTENER.

Application filed. February '7, 1924. Serial No. 691,136.

To all whomwz't may concern:

Be it knownthat I, LOUIS A. LUPIEN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to head coverings in which provision is made for varying the size of the headband, and the objects of the invention are to provide simple, practical inexpensive and easily applied means by which these adjustments can be quickly made and which will automatically lock and be retained in adjusted relation.

These objects are attained by certain novel features of construction, combinations and relations of parts as will be clear from the following specification.

The drawing accompanying and forming part of the specification illustrates the invention embodied in several different forms and it should be understood that the structure may be further varied without departure from the true spirit and scope of the invention as hereinafter defined and claimed.

Figure 1 is a front view of a cap showing one form of the invention applied thereto.

Figure 2 is a longitudinal sectional view of the adjustable clasp construction as taken on substantially the plane of line 22 of Figure 1.

Figures 34, 56 are sectional andfront views respectively of modified forms of the clasp construction.

The capor head covering may be of any usual or special construction, except that it has a head-band 15 which is adjustable by means of the overlapping tabs 16, 17 provided at the front of the cap and carrying the cooperating parts of an adjustable clasp.

All of the several forms of clasps shown are alike in that they each consist of a keeper plate 18 secured to one of the tabs provided with seats or openings 19 to receive a projecting hook or tongue 20 carried by a plate 21 attached to the other tab.

In the first form of the invention disclosed the keeper plate is made with raised beads or shoulders 22 about the rims of the adjustmentopenings 19 and the shank of the hook 520 is made with adepression 23 which snaps over these heads when the hook is engaged in the openings, as indicated in Figure 2, to operate asa spring lock yield edges of the keeper plate. As will be clear from Figure 3, before this form of catch can be released, the base of the hook must be pulled away from the face of the keeper plate to release the lugs 24 from the holes 25 and then the hook can be shifted longitudinally to spring it out of the opening in which it is engaged.

The structure of Figures 5 and 6 is like that just described except that the additional locking points 24 are carried at the ends of spring fingers 26 extended from the forward edge of the plate 21. With this construction itis simply necessary to apply sufficient endwise pressure to the hook to force the spring tongues out of the holes 25 and to overcome the holding tension of the spring hook. In all the forms of the invention the adjustments are quickly and easily effected and when. the adjustment is made, the parts are automatically locked by a spring snap action and will stay so until purposely released. The desirable features of simplicity and low cost are also present in the various forms of the invention.

What I claim is:

1. A fastening device comprising a keeper plate having adjustment openings therein and upstanding shoulders surrounding the rims of such openings and a hook engageable in said openings having a shank with a depression therein to snap over in back of such shoulders when the hook is engaged in the openings.

2. A fastening device comprising a keeper plate having adjustment openings therein and upstanding shoulders surrounding the rims of such openings and a hook engageable in said openings having a shank with a depression therein to snap over in back of such shoulders when the hook is engaged in the openings, the keeper plate having openings at the sides of the hook receiving openings and the hook member carrying inwardly extending lugs engaging in the latter openings to retain the shank of the hook sprung in engagement With the shoulders.

3. A fastening device comprising a keeper plate having adjustment openings and looking openings at opposite sides of the adjustment openings and a hook engageable in the adjustment openings and having a shank, inwardly extending lugs at opposite sides of the hook shank engageable in the lock ing openings to secure the hook against longitudinal disengagement from the ad justment openings and to prevent twisting of the hook With respect to the keeper plate.

4. A fastening device comprising a keeper plate having adjustment openings and look ing openings at opposite sides of the adjustment openings and a hook engageable in the adjustment openin s and having a shank, inwardly extending lugs at opposite sides of the hook shank engageable in the locking openings to secure the hook against longitudinal disengagement from the adjustment openings and to prevent twisting of the hook with respect to the keeper plate, the locking lugs being carried by independently yielding spring fingers located at opposite sides of the hook.

In testimony whereof I affix my signature.

LOUIS A. LUPIEN.
